The scale of the Internet and the availability of many different social networking platforms makes it a challenge to stand out from the crowd. Announcing you're looking for a new position through a social network could also damage your career if you already have a job. Some employers may view social networks as having little relevance to them or their business, so you're more likely to get on board with these organizations through traditional means. Managing an online presence effectively across multiple social networking platforms also takes a great deal of time and commitment.
